caudice incrassato ; foliis primariis ovatis oblongisve subintegerrimis, sequentibus ly- 

 rato-pinnatifidis lobo terminali oblongo-lanceolato vel lineari-lanceolato ; tubo caly- 

 cis prselongo ; capsulis sessilibus ovatis tetragono-alatis lignescentibus Isevibus ; se- 

 minibus angulatis testa suberosa incrassata. — Between Western Texas and El Paso ; 

 in fruit. Also in the collection of 1851, in flower, and with a few capsules of the 

 preceding year. — The branching, creeping caudex is from one third to half an 

 inch in diameter. Leaves crowded, cinereous or canescent Avith a fine and close pu- 

 bescence, glabrate above with age, petioled ; the earlier ones (as seen in the coll. 

 of 1851) mostly entire or repand, with the lamina two inches or less in length and 

 sometimes an inch wide ; the succeeding ones narrower and mostly pinnatifid ; the 

 entire or toothed terminal lobe prolonged, 2-4 inches in length. Tube of the ca- 

 lyx 5 or 6 inches long, rather stout, much as in the section Pachylophis, as like- 

 wise, apparently, is the flower; except that the petals (18 lines long) seem to have 

 been pale yellow, changing to rose-color in fading. Capsules closely sessile on the 

 caudex, from half to three quarters of an inch in length, and nearly half an inch in 

 diameter, of a thick, crustaceous texture, acute, but blunt at the apex, scarcely if 

 at all reticulated, the sides broad and not at all ridged, the narrow wings or 

 wing-like angles perfectly smooth and even, thickish, loculicidally 4-valved at the 

 apex, the valves not pointed. Seeds numerous, large, closely packed in two rows in 

 each cell, which they entirely fill, strongly angled by mutual pressure ; the testa 

 very thick and corky, especially toward the chalaza ; Avhere in the young seeds is 

 seen a sort of thick double crest with a denticulate edge, which is nearly obliter- 

 ated when mature.

197. (E. (Meriolix v. Salpingia) tubicula (sp. nov.) : minutissime glanduloso- 

 puberula, humilis ; caulibus sufl'ruticosis ramosis diff'usis ; foliis lanceolatis lineari- 

 oblongisve planis glabellis sessilibus integerrimis ; calycis tubo infundibular! lacin- 

 iis ovarioque vix duplo longioribus ; petalis orbiculato-obovatis ; capsulis clavato- 

 cylindraceis inferioribus subpedunculatis. — Prairies beyond the Pecos ; Aug. Al- 

 so gathered in larger and much better specimens in the collection of 1851. — Stems 

 a span to a foot high, bushy, at first erect, at length diff"use, puberulent, as is the fo- 

 liage, &c., with a very minute viscous glandulosity, nearly glabrous to the naked eye. 

 Leaves from half an inch to an inch long, and one to three lines wide, bright 

 green, thin. Tube of the calyx from one third to half an inch long, little longer 

 than the broadly triangular-lanceolate lobes, which are not carinate nor marked 

 with a salient midnerve. Petals 4 to 6 lines long, much dilated and roundish, yel- 

 low. Capsules half an inch long, not thicker than packthread. Seeds ovoid- 

 oblong, with a thin and smooth inappendiculate testa. — This species may as well be 

 referred to the section Meriolix as to Salpingia, and indicates the propriety, in a re- 

 vision of the genus, of admitting the latter as a subdivision only of Meriolix.
